Divorce Looming for Nick Cannon and Mariah Carey?

It turns about Nick Cannon and Mariah Carey’s storybook romance has entered a dark chapter, with Goss Gawkers squealing that the unlikely love story between the aging songbird and the much-younger actor is presently in its final act.

Nick and Mariah dated for just two months before tying the knot in 2008. They are the parents to three-year-old twins, Monroe and Morrocan. Taken aback by what’s been described as Cannon’s “wandering eye” and his knack for oversharing about his real and wishful conquests with other divas, Mariah has effectively kicked Nick out of the couple’s New York home with plans to file for divorce just weeks away.

Dish about the Mr. and Mrs.’ parting of the ways are spreading across the blogosphere like wildfire. And, if In Touch Weekly tattles are to be believed, the in-fighting is about to get nasty.

“Mariah has had several closed door meetings with divorce lawyers. But Nick’s being more passive. He’s less inclined to pull the trigger, perhaps because of the kids. He’ll definitely wait for Mariah to file for divorce, but he won’t go down without a fight. He wants a chunk of her $500 million fortune.”

TMZ reports the two separated in May. Mariah, 45, was allegedly incensed when Nick appeared on Big Boy’s Neighborhood and named five famous women he had “been with” in the past. Naturally, he name-dropped a few of his high-profile exes, including Christina Milian, Serita Ebanks and Kim Kardashian. Then there was the time he did an interview with Australian radio station 2DAYFM, where he admitted that he wished he could have added his America’s Got Talent co-star Mel B to his lengthy list of well-known sexual conquests.

A loose-lipped informant tells The New York Post’sPage Six Column that Mariah hired an arsenal of security guards to keep an eye on 33-year-old Nick during a Las Vegas pool party earlier this year. History says Mariah had good reason to be concerned. After all, the Wildin’ Out star was pegged as a notorious womanizer after his romance with Milian went up in smoke.

“The security guard wasn’t there to keep the girls away from him. It was to keep him away from the girls…He hasn’t been staying at their home. He’s been living out of hotels. They’re fighting a lot.”

E! claims all that fighting is why the couple’s homes in Los Angeles and the Bahamas are currently on the market.

Neither camp is talking, but as of last weekend, Nick was still wearing his wedding ring.
